<span style="color: red; ">requestScope.requestStr: </span>${requestScope.requestStr} <br>
<span style="color: red; ">pageScope.pageContextStr:</span> ${pageScope.pageContextStr} <br>
<span style="color: red; ">param:</span> ${param}<br>
<span style="color: red; ">param.name:</span> ${param.name}<br>
<span style="color: red; ">paramValues.like[0]:</span>${paramValues.like[1]}<br>
<span style="color: red; ">head(headValues): </span> ${header["Accept-Language"]}<br>
